To all 'whom t may concern.'

Re it known that I, ROBERT T. JOHNSTON, a citizen of the United States,residing at Plaineld, in the county of Union and State of New Jersey,have invented a new and useful Inking Apparatus vfor Printing Presses,of which the following is a speciiication.

The object of this invention is to provide an improved arrangement ofinking apparatus for a printing press employing a reciprocating bedcarrying a Hat form or forms, cooperating with which is an impressionmechanism comprising one or more impression cylinders.

I have invented a new arrangement of inking mechanism which has all theadvantages and perfection of the cylinder inking mechanism and all theconveniences of the table distributing mechanism. To accom plish thisdesirable end, I arrange the inking vmechanism as follows -The inkdistributing device is arranged adjacent to the impression cylinder andthe form inking rollers, in the position practically the same as thatused with cylinder distribution. The ink-fountain and ductor, however,are ar` ranged at the front end of the press remote from theink-distributing device in the position used in table distribution. Anink-carrier is provided and operated between the ink-supply and inkdistributing device preferably by being attached to the reciprocatingbed, which carrier in the best form now known to me consists of a smallink-plate depressed below the level of the forms so as not to contactwith the form inking rollers, or of an ink-carrying plate placed so farout that it will not reach the outside form inking roller when the bedis in its eXtreme forward position. A connecting device, such as avibrating roller, is provided to take the charge or daub of ink from theand supply the same to the inkdistributing device. The distributingdevice and the form inking rollers are arranged so that they areconnected at least for a period substantially equal to one full inking'of the forms by the form inking rollers. With this arrangement, the forminking rollers, when performing their function of inking the forms, onone stroke of the bed, at least, are connected to the ink distributingdevice and have behind them the full charge of distributed ink in thedistributing device. By thus enabling the form inking rollers to supplya continued full charge of digested ink to the forms for their entirelength, the objection of light printing toward the tail of the sheets isovercome. The connecting device between the ink distributing device andthe form inking rollers is arranged to operate in connection with theink distributing device, the form inking rollers, and the period ofconnection and disconnection between the latter, so that the undigestedink cannot pass through the distributing device to the form inkingrollers, but must remain in said distributing device and be thoroughlydigested and worked up before passing to said form inking rollers. Thisnew arrangement further enables me to dispense with the plurality ofdistributer rollers sometimes employed in connection with each pair ofform rollers. In other words, in some of the prior table distributiondevices, to overcome, to some measure, the difliculty of light inking aplurality of distributer rollers have been piled up on top of each pairof form inking rollers to increase in some measure the reservoircapacity adjacent to the impression mechanisi This only in a slightdegree tends to relieve the distributing de vice of its work and numberof rollers. Vhile in my new arrangement the distributing device acts notonly to perform the function of working the ink out into an even film,but additionally acts as a reservoir for the form inking rollers at theproper time. To overcome the second difficulty encountered in theprevious forms of inking mechanism where the distributing device wasarranged close to the impression cylinder and form inking rollers, Iplace the various rollers which make up the distributing device inframes so mounted that the various rollers are very accessible forreplacement and cleaning. By these two improvements I have provided aninking mechanism which has substantially all the advantages of cylinderdistribution and of table distribution without the disadvantagespreviously inherent in either.

My improvement may be worked out in various ways which classifythemselves as follows: first: the distributing device may be rotary inaction; second: the distributing device may be oscillating in action. Inthe first class the distributing device may (a) alternately make andbreak connection with the form inling rollers (ZJ) may have two paths oftravel for the ink, each path alternately connecting to the form inlringrollers; or (c) the distributing device may be connected at all t-'meswith the form inking rollers, and the latter operated so as to contactwith the forms upon the movement of' the bed in one direction only; or,as a modification, two sets of form inking rollers may be used andconnected at all times with the distributing device, one set of forminking rollers being moved to contact with the forms upon the movementof the bed in one direction, and the other set of form inking rollersbeing moved to contact with the forms upon the movement of the bed inthe other direction. In this application for patent generic claims aremade to cover both classes and the three types of the first class andspecific claims to species (a) of the first class thereof, whichspecific construction is shown and described. It is to be understood,however, that the broad claimsl made in this case cover both classes andthe various species hereinbefore pointed out.

Referring now to the drawings which show said specific arrangement of myinvention, and which I believe is the best form for practising the same,Figure 1 is an elevation of the principal parts of a two-revolutionsingle cylinder printing machine with my improvement applied thereto.Figs. 2, 3 and 4 are detail views of the cams used to operate thevarious parts of the inking mechanism. Figs. 5, 6 and 7 are detail viewson an enlarged scale illustrating the frames in which the rollers of thedistributing device are arranged, and Figs. 8 to 13 inclusive arediagrams illustrating the operation of the device.

Referring to the drawings and in detail A designates the reciprocatingbed, and B the impression cylinder of an ordinary tworevolution singlecylinder printing machine. C designates the delivery table arranged atthe front of' the machine. D designates a set of tapes onto which thesheets pass from the impression cylinder, and from which they aredelivered by an ordinary delivery mechanism, such as an oscillating flyframe E. 10, 11, 12 and 13 designate form inking rollers arranged closeto the impression cylinder. Arranged to cooperate with the form inkingrollers are distributing rollers 111, 15 and 16. All these parts arearranged .and connected as is common in printing machines of this typeand need not be described at length.

In practice, the distributer rollers 14,. 15 and 16 are geared to thereciprocating bed in the usual manner, and have the usggal-cam or screwdevices for vibrating "{mgcsam axially. By this arrangement the Crm k'ing rollers will be oscillatory in actikqn to ink the ward and backward.

G designates an ink distributing device made up of a series of rollers.This distributing device, it will be noted is arranged close to the forminking rollers and close to the impression cylinder. The distributingdevice is made up of three metal or distributer rollers 17, 18 and 19and three composition rollers 20, 21 and 22. The metal distributerrollers may have any of the usual cam devices employed with thedistributer rollers used in the ordinary cylinder distribution so thatthey will be vibrated to and fro axially as they rotate. The distributerrollers 17, 18 and 19 are journaled in frames 23 which are pivoted tothe main framing of the machine as at 24:, and which frames are tiedtogether by a rod 25- These frames are usually provided with hooks 2G tocarry the distributer roller 16 which coperatcs with the form inkingrollers 12 and 13. 'Ihe distributer rollers 17, 18 and 19 have pinionsor gears 27 on their shafts, and by means of intermediates 28 and 29journaled on studs secured in one of the frames 23 the same are gearedtogether. The gear on the distributer 19 meshes with a gear 30 securedon the pivot of one of the frames 23. This gear is positively rotatedduring the operation of the press by gearing hereinafter described, andby this arrangement the distributer rolls will be positively andcontinuously rotated in one direction. The composition rollers 20, 21and 22 are mounted in hooks secured to supplemental frames 31 p-ivotedat 32 to the frames 23. Stops 33 are arranged on said frames 23 andsupplemental frames 31 to limit the pivoting movement of thesupplemental frames. By this arrangement the frames can be moved to theposition shown in Fig. 6 if it is desired to clean the distributerrollers 17, 18 and 19, or can be moved to the position shown in Fig. 7if it is desired to remove the composition rollers 20, 21 or 22. rlhesupplemental frames 31 are provided with sockets 34 below the hookswhich carry the composition rollers 20, 21 and 22, so that when theparts are moved to the position shown in Fig. 7, said Icompositionrollers are in position to be easily removed, and so that the same canbe replaced by simply putting the shafts thereof in said sockets. Byturning the parts to the. position shown in Fig, 6, or to the positionshown in Fig. 7, all the contacts in the distributing device can bebroken, which is desirable when the press is to be left out Vofoperation. It will be noted that the distributer 16 has considerableplay in the forms as the bed travels both 'foi if ,with adjusting screwshooks 26. By this arrangement the said distributer can make constantcontact with the form inking rollers 12 and 13, and the contact betweensaid distributer roller 16 and the composition roller 2O can be brokenby slightly raising the frames 23. The raising and lowering of theframes to make or break the contact at this particular point does notinterfere with any of the contacts between the rollers of thedistributing device which are thus left free to run and continuouslygrind up and distribute the ink. The frames 23 are provided with hooks35 at their free ends which are useful for taking out or replacing therollers. When the frames 23 and supplemental frames 31 are raised to theposition shown in Fig. 6 or Fig. 7, the delivery tapes D may be liftedup out of the way as indicated in dotted lines in Fig. 1, or in somecases, the tapes are arranged far enough above the frames to allow themto be swung up Linder the same.

An ink-fountain II is arranged at the front end of the press in theusual position in table distribution. This fountain may be of the usualconstruction and provided to adjust its supply at various points axiallyof its roll, and may be provided with the usual mechanism for giving theroll thereof a partial turn for each reciprocation of the bed.

A ductor roll 36 is arranged in arms 37 which are pivoted to theframing, and which are operated by the connections hereinafterdescribed.

At t-he eXtreme forward end of the bed is arranged an ink-carrier Iwhich consists of a small plate arranged at a level below the forms. Theductor roller 3G is arranged to deposit a daub of ink from the inkfountain roll upon this carrier.

An ink conveying composition roller 38 is arranged in arms 39 which aresecured to a shaft journaled in the frame of the ma? chine, so that saidink conveyer roller 38 is in position to contact with the distributer 19of the ink distributing device or with said ink carrier I. This inkconveyer roller is operated by said connections hereinafter described.

The gearing for driving these parts may be arranged as follows r`40designates the driving shaft which by means of gear 41 and intermediate42 drives the gear on the impression cylinder. Motion is alsocommunicated from said driving` shaft 40 to the gear 43 which engagesupper and lower racks carried by the bed to give the bed itsreciprocating movement. Motion is also communicated from said drivingshaft 40 by means of a gear 44, pinion 45 and gear 46 to a shaft 47,this last gearing being so arranged that said shaft 47 makes onerevolution for each complete reciprooation of the bed. Motion is alsocommunicated from said driving shaft 40 by means of miter gears 48,shaft 49, and miter gears 50 to a gear 51 which meshes with the gear 30on the pivot 24 of the frames 23. By this last mentioned gearing therollers of the distributing device will be continuously turned in onedirection and the gearing is so proportioned that their peripheral speedwill be equal to the speed of the reciprocating bed when the same isprinting. On said shaft 47 are arranged cams 52 engaging which arerollers mounted on the end of pivoted arms 53. Pivoted to these arms arerods 54 which extend up through bearings inside of the framing of themachine, and the ends of these arms project up in position to engage theends of the frames 23. By this construction the distributing devicewillvbe moved slightly about its pivot by the cams 52, and the contactbetween the rollers 2O and 16 broken at the proper time so that thedevice will work as hereinafter described. Also arranged on said shaft47 is a cam 55 engaging which is a roller se cured on a yoke 56 whichconnects to a pivoted arm 57 arranged on the shaft which carries thearms 39 of the ink conveyer roller 38. By this mechanism the inkconveyer will be operated between the ink carrier I and the distributerroller 19, so that the device can operate as hereinafter described. Alsoarranged on said shaft 47 is a cam 58 engaging which is a roller on theend of a yoked rod 59 which connects to an arm on the shaft whichcarries the arms 37 which carry the ductor 36. By this arrangement theductor roller 36 will be operated as hereinafter described. Springs areemployed as indicated to keep the various rollers against theirrespective cams.

This hereinbefore described gearing and operating connections are onlyshown in outline as the same are well understood and as this .showing issufficient to enable a printing press mechanic to understand theoperation thereof.

The operation of the mechanism can be followed from the diagrams Figs. 8to 13 inclusive. In Fig. 11 the ductor roll is shown as applying' a daubof ink taken from the roll of the ink fountain H to the ink carrier I.This ink is retained by said carrier I until the same is t-aken up bythe ink conveyer roller 38 on the return stroke of the bed, as indicatedin dotted lines in Fig. 9. This daub of ink is then given to thedistributer roller 19 of the ink distributing apparatus, and is groundup and distributed into a thin film by the distributer rollers 17, 18and 19 and the composition rollers 20, 21 and 22 of the ink distributingapparatus as they constantly rotate. From the distributing device theink is applied to the form inking rollers, and by the latter to theforms in the following manner. In Fig. 8,

the bed is shown at the end of its forward stroke and as having printeda sheet, so that the forms in this position are cleaned of ink. The bednow moves backward, toward the fountain, and at the position shown inFig. 9 acquires its full speed movement in this direction. As soon asthis full speed movement is acquired the frames 23 are slightly lowered,thus making contact be tween the composition roller 2O of the inkdistributing device and the distributer roller 16 of the form inkingrollers, or thus connecting the ink distributing device to the forminking rollers. Now as the bed conn tinues its movement toward theink-fountain the form inking rollers will ink the.

forms, and the continued or repeated rotation of the form inking rollerswhile inking the forms will not cause a diminution of the ink supply asthe form inking rollers are locked to the ink distributing device'. Thisaction continues until the bed reaches the right hand limit of its fullspeed movement toward the ink fountain, as shown in Fig. 10, when theretardation of the movement of the bed commences. At this point theframes 23 are slightly raised to break contact between rollers 1G and20. This will not interfere with a continued full charge of ink beinggiven to the forms, as the saine have already passed under the twoforward form inking rollers 10 and 11, and nearly clear of the forminking roller 12, and the point of contact of the form inking roller 13is less than its circumference away from the gripper edge of the forms.The bed non, reverses its movement at its right hand extreme near theink fountain as shown in Fig. 11, and thus acquires its full speedmovement to the left at the point indicated in Fig. 12. This full speedmovement causes the printing so soon as the gripper edge of the formsengages the impression cylinder, which printing movement continues untilthe full speed movement of the bed to the left is linished as shown inFig. 13. During this forward movement of the bed, as the forms passunder the form inking rollers the full and even charge of ink which theforms received as the bed moved toward the ink fountain will not bedisturbed, but will be perhaps a little more evenly spread. The bed isretarded from the posit-ion shown in Fig. 13 to its extreme of travel orthe position shown in Fig. S, from which position thc operation justdescribed is repeated. Thus it will be seen that the forms are inked bythe form inking rollers while the same are connected to the distributingdevice, so that there is substantially a full and complete inking forthe entire length of the forms on the backward stroke of the bed. Thedaub of ink is applied by the connecting roller 3S to the distributer 19just as the left-hand edge of the ink-carrier passes by said connectingroller 38 on the movement of the bed toward the ink-fountain. This daubof ink will be carried forward through the distributing device, butbefore the same reaches the composition roller 20 connection will bebroken between said composition roller 20 and the distributer 16 of theform inking rollers, whereby the daub of ink cannot pass through thedistributing device to the form inking rollers, but must remain in saiddistributing device and be thoroughly digested and worked up beforepassing to said form inking rollers. Thus the advantageous resultshereinbefore particularized are neatly and mechanically obtained.

If desired, a small ink spreading table T may be carried by the bedbetween the inkcarrier and the forms for the purpose of evening the inkamong and between the form inking rollers, as is shown in dotted linesin Fig. 10. This ink spreading table performs no function of carryingthe ink from the .fountain to the distributing device, or from thedistributing device to the form inking rollers, but is Simply added forthe purpose stated.

A particular advantage of the structure using a rota-ry distributingdevice resides in the fact that the rollers of the ink distributingdevice run at the highest speed possible continuously during theoperation of the machine, whereby the ink is distributed into a veryfine .and even film before it is given to the form inking rollers.

As before stated, the ink distributing device may be arranged to work inseveral different ways.

The details herein shown and described may be greatly varied by askilled mechanic without departing from the scope of my invention asexpressed in the claims.
